1, sealing strip is laminated structure, and terminal box exists stainless steel otch, easily causes damage to sealing strip, affects sealing effectiveness;
2, terminal box door-plate undercapacity, casing overall precision is not high, produces deformation under long-term operating mode, and form door-plate and cave inward at lockset place, the bad template that upper and lower two angles are outwardly, causes producing gap between the sealing strip of sheet and casing;
When 3, being applied to outdoor environment, owing to affecting by harsh and unforgiving environments such as difference variation for a long time, gum viscosity declines, and sealing strip installation site can be caused not fix, affect sealing effectiveness.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of isolating switch terminal box hermetically-sealed construction.
The utility model realizes in the following way:
A kind of substation isolating-switch terminal box hermetically-sealed construction, described hermetically-sealed construction comprises sealing plate and is arranged on the sealing frame at sealing plate edge; Described sealing frame comprises three sidewalls, and the sidewall on both sides is connected from the different edges of center side wall respectively, forms two clip slots that opening direction is contrary; Described sealing plate is connected with one of them sidewall of sealing frame.
Above-mentioned hermetically-sealed construction, described sealing plate is one-body molded with sealing frame.
The utility model has following beneficial effect:
1, sealing frame and sealing plate coordinate, and ensure housing interior volume and external environment, greatly improve sealing property, avoid the grains of sand to enter casing;
2, the different clip slots in same sealing frame clamp the side of casing and the side of chamber door respectively, on the one hand chamber door and casing are played a protective role, prevent hermetically-sealed construction damaged, also extend the distance hindering the grains of sand to enter box house on the other hand, ensure that sealing effectiveness;
3, hermetically-sealed construction of the present utility model does not adopt bonding mode, naturally also just avoids the adhesive bond failure that environmental change causes.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the utility model hermetically-sealed construction.
In above-mentioned Fig. 1,1, sealing frame; 2, sealing plate; 11, clip slot; 12, sidewall.
Embodiment
For the defect that prior art exists, to be described in further detail of the present utility model below in conjunction with accompanying drawing for the ease of it will be appreciated by those skilled in the art that:
The utility model provides a kind of substation isolating-switch terminal box hermetically-sealed construction, the ethylene propylene diene rubber (EDPM) adopting the reclaimed rubber that undopes is main material, ensureing under good insulation property prerequisite, the resistance to weather performance that ethylene propylene diene rubber is good and impact elasticity can cooperatively interact with hermetically-sealed construction of the present utility model, and sealing property is further enhanced.
Hermetically-sealed construction of the present utility model as shown in Figure 1, comprises sealing frame 1 and sealing plate 2; Sealing frame 1 comprises three sidewalls 12, and the sidewall 12 on both sides is connected from the different edges of center side wall 12 respectively, forms two clip slots 11 that opening direction is contrary; Sealing frame 1 is the annular adapted with chamber door, and the sidewall 12 near sealing frame 1 center is connected with sealing plate 3; Sealing frame 1 is one-body molded with sealing plate 3, realizes seamless link, ensure that the seal of hermetically-sealed construction.
In the present embodiment; three sidewalls 12 of sealing frame 1 be arranged in parallel; the opening of clip slot 11 is slightly less than the thickness of casing/chamber door side; the friction between side otch and sealing frame 1 is increased further with this; subtract the momentum to base portion 11 when otch inserts, better can protect the main material integrality of the rubber of hermetically-sealed construction.When hermetically-sealed construction of the present utility model is applied to the comparatively smooth round and smooth casing of some side otch, for ease of installing, also the sidewall 12 on sealing frame 1 both sides can be obliquely installed, form the clip slot 11 that opening large inner is little.
When the utility model uses, need to be inserted clip slot 11 by the side of the casing sealed, meanwhile, the side of chamber door inserts the groove contrary with above-mentioned clip slot 11 opening direction and presss from both sides 11.By the sealing frame 1 that clip slot opening is contrary, realize fitting tightly of chamber door and casing.Sealing frame 1 plays a protective role for chamber door and casing, prevents hermetically-sealed construction damaged, also contributes to reducing chamber door deformation; Meanwhile, the clip slot 11 that opening is contrary also extends the distance hindering the grains of sand to enter box house, ensure that sealing effectiveness.
Sealing frame 1 and sealing plate 2 one-body molded, space, sealing plate 2 sauce casing inside and outside isolates, and now, box house only has the clip slot 11 along sealing frame 1 to communicate with the gap of casing side with outside, this considerably increases the difficulty that the grains of sand enter casing, improve sealing property.Owing to not adopting bonding mode in installation process, naturally also just avoid the adhesive bond failure that environmental change causes, the phenomenon that sealing strip comes off can not occur.
To sum up, the utility model adopts clip slot 11 to be clamped by casing side otch, prevents hermetically-sealed construction damaged; The side of chamber door encases by another clip slot 11, improves sealing property while reducing the probability of chamber door distortion; Three sidewalls 12 are distribution in " S ", adds the grains of sand and enters difficulty in case, avoid " laying dust phenomenon " that existing terminal box often has, eliminate time and the operation of labor cleaning.
